Kennametal 5647194 Hydraulic Chuck CAT40 Taper Shank

Product Description

The KENNAMETAL 5647194 is a hydraulic tool chuck with a CAT40 taper shank, designed for precision workholding in CNC machining centers. The hydraulic clamping mechanism delivers consistent radial grip force around the tool shank, reducing runout and improving surface finish in milling, drilling, and reaming operations. The chuck features a 65 mm nose diameter, a 51 mm clamping depth, and through-coolant capability for directing cutting fluid directly to the tool tip. Overall length measures 169.85 mm. This chuck is installed by machining center operators and setup technicians in production and job-shop environments.

This hydraulic chuck is suited for CAT40 spindle applications in both vertical and horizontal machining centers. It accepts tool shanks with a 1-1/4 inch hole diameter and a 1-3/4 inch shank diameter. The 4-inch projection makes it appropriate for applications requiring reach into deeper cavities or fixtures. Through-coolant support makes it a practical choice for high-speed and high-temperature cutting operations where coolant delivery at the cutting edge is required.

Key Features

• CAT40 taper shank for direct spindle mounting on compatible machining centers
• Hydraulic clamping with 51 mm clamping depth for secure, low-runout tool retention
• 65 mm nose diameter with 2.559 inch decimal equivalent
• Through-coolant design routes cutting fluid directly to the tool tip
• 4-inch projection for extended reach applications
• Accepts 1-1/4 inch hole diameter and 1-3/4 inch shank diameter tooling

Compatibility

Designed for use with CAT40 spindle-equipped CNC machining centers accepting hydraulic tool chucks with a 1-1/4 inch bore and 1-3/4 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machining center operator or toolroom technician. Power down and lock out the machine spindle before mounting or removing the chuck. Use the appropriate CAT40 retention knob and torque it according to machine tool builder specifications. Inspect the spindle taper and chuck taper for contamination or damage before seating; even minor debris will affect runout and clamping performance.
